In a measurement system that comprises plural measurement devices classified by groups, and plural data processing devices on a network that receives and processes measured data from the measurement devices, the data processing devices are smoothly allocated. The measurement devices belong to groups based on the areas in which they are located, and respectively transmit measured data to a multicast address defined for each of the groups to which they belong. A management device detects an overloaded or failed data processing device, stops data processing on a multicast address at which the data processing device receives data, alternatively commands another less loaded data processing device to join the multicast group, receive measured data transmitted to the multicast address, and process the data.
Legal claims defining the scope of protection, as filed with the USPTO.
1. A measurement system comprising: a plurality of measurement devices connected over a network, each of the measurement devices belonging to any one of a plurality of groups, and transmitting measured data to a multicast address which corresponds to a group to which the respective measurement device belongs; a plurality of data processing devices that receive the measured data of which the destination is the multicast address which corresponds to the group assigned to each data processing device, and that perform data processing based on the measured data; and a management device which decides the groups in which the data processing devices are to join, based on the join status of the data processing devices to the groups and load amounts of processing on the groups in which they are joined, and assigns at least one of the data processing devices to either of groups based on respective operating statuses of the data processing devices; wherein the plurality of measurement devices are classified into groups, based on the disposition positions of the respective measurement devices.
2. The measurement system according to claim 1 , wherein each of the plurality of groups has priority on the data processing.
3. The measurement system according to claim 2 , wherein the priority is decided based on the result of the data processing.
4. The measurement system according to claim 1 , wherein at least one of the measurement devices belongs to the plurality of groups, and transmits measured data to a plurality of multicast addresses defined for each of the groups.
5. The measurement system according to claim 1 , wherein a measurement target area of the measurement system comprises a plurality of areas, wherein the measurement devices are classified into groups, based on the disposition positions of the measurement devices in each of the areas, wherein at least one terminal can move within the plurality of split areas, wherein the measurement devices of the groups corresponding to the areas perform measurement on the terminals existing in the areas, and wherein the data processing devices joined in the groups receive the measurement data, and perform data processing.
6. The measurement system according to claim 5 , wherein the one data processing device joins the plurality of groups, receives the measured data measured in the plurality of areas, and performs the data processing.
7. A management device, in a measurement system including a plurality of measurement devices connected over a network, and a plurality of data processing devices that receive data measured by the measurement devices and perform data processing, comprising: a data processing device information storage part which holds information about multicast addresses each assigned to each of the groups with respect to the measurement devices respectively belonging to specific groups; and a processing allocation part which assigns at least one of the groups to the data processing device, and which sends, to the data processing device, an instruction to receive measured data of which the destination is the multicast address which corresponds to the group assigned to the data processing device and to process the measured data; wherein the plurality of measurement devices are classified into groups, based on the disposition positions of the respective measurement devices, wherein the data processing device information storage part stores the respective operating statuses of the data processing devices, and information about groups of the join destinations, and wherein the processing allocation part decides the groups in which the data processing devices are to join, based on the join status of the data processing devices to the groups and load amounts of processing on the groups in which they are joined.
8. The management device in a measurement system according to claim 7 , wherein the data processing device information storage part stores the respective operating statuses of each of the data processing devices, and information about groups of each of the join destinations, and wherein the processing allocation part allocates the plurality of groups according to priority of the data processing.
9. The management device in a measurement system according to claim 8 , wherein the processing allocation part decides each of the priorities, based on the data processing result.
10. A processing distribution method in a measurement system which includes a plurality of measurement devices connected over a network, a management device, and a plurality of data processing devices, the method comprising the steps of: assigning, by the management device, the data processing devices to respective ones of a plurality of groups based on respective operating statuses of the data processing devices; transmitting, by the measurement devices, measured data to multicast addresses corresponding to each of the groups to which the measurements devices belongs; receiving the measured data, by the data processing devices, as the destinations related to the multicast addresses which correspond to the groups; performing, by the data processing devices, data processing based on the measured data; deciding, by the management device, the groups in which the data processing devices are to join based on the join status of the data processing devices to the groups and load amounts of processing on the groups in which they are joined; and re-assigning, by the management device, at least one of the data processing devices to any of the groups based on respective operating statuses of the data processing devices; wherein the plurality of measurement devices are classified by groups, based on the disposition positions of each of the measurement devices.
11. The processing distribution method according to claim 10 , wherein the plurality of groups have priorities on the data processing.
12. The processing distribution method according to claim 11 , wherein each of the priorities is decided based on the data processing result.
